Apple on Monday delivered the promised update to patch the ‘Shellshock’ Bash bug in OS X. You can download the update manually here, otherwise it should be popping up in the Updates tab of the Mac App Store shortly.

The security flaw was uncovered by security researchers last week and sent much of the Internet into a panic. Affecting the bash command shell in UNIX, the exploit allows for hackers to remotely execute malicious code.

Still we recommend grabbing today’s update as soon as possible. Again, Mavericks users can find it here, and OS X Lion, OS X Mountain Lion users can find it here and here. There is no update for OS X Yosemite as of yet.
